[oXygen-user] validation failure with version 6.1

[George Cristian Bina]

Hi Gary,

The problem in the first case appears because you use different schema 
locations for the xml namespace, thus two schemas are parsed and you get 
the duplicate definitions. You should decide if you want to use xml.xsd 
or http://www.w3.org/2001/03/xml.xsd and use the same in all the schemas 
that import the xml namespace. Changing for instance in the 
simpledc20021212.xsd schema the import for the xml namespace as below
<xs:import namespace="http://www.w3.org/XML/1998/namespace"
              schemaLocation="xml.xsd">
will solve the duplicate definitions problem.

Also note that the http://www.w3.org/2001/03/xml.xsd stores the latest 
schema for the xml namespace and that may vary in time, see the comments 
in the http://www.w3.org/2001/03/xml.xsd schema for more details about this.

Best Regards,
George
